摘要： The described apparatus has utility as a doctor on a paper machine, as a drying element in an aircap dryer and as a sealing element in such a dryer. It involves a foot portion having an outer surface generally conforming to the curvature of the cylinder surface on which it is used. It is resiliently supported in close juxtaposition to the cylinder surface so that a gap diminishing in thickness towards one longitudinal edge of the foot portion is provided. At least two rows of nozzles communicate through the foot portion in order to project pressurized air into the gap. Each nozzle is angled relative to three orthogonal planes, one of which is tangent to the cylinder surface at the point where the nozzle axis meets the surface, another of which is parallel to the longitudinal edge of the foot portion. The flow from the nozzles is such as to support the foot portion and to seal the support flow from any disorganized flows. The jetting air will tend to aid in doctoring a paper sheet from the cylinder surface or to dry a paper sheet passing thereunder or to seal an opening from the passage of air therethrough if the opening is defined by a cylindrical surface.
摘要翻译：所描述的装置在造纸机上作为医生使用，作为空气干燥器中的干燥元件和这种干燥器中的密封元件。它涉及一个足部，其外表面大体上与其所使用的气缸表面的曲率一致。它被弹性地支撑在与气缸表面紧密并置的位置，从而提供朝向脚部的一个纵向边缘的厚度减小的间隙。至少两排喷嘴通过脚部连通，以便将加压空气投射到间隙中。每个喷嘴相对于三个正交平面成角度，其中一个垂直平面在喷嘴轴线与表面相接的点处与圆柱体表面相切，另一个平行于底部部分的纵向边缘。来自喷嘴的流动是为了支撑脚部并且密封来自任何混乱流动的支撑流。如果开口由圆柱形表面限定，喷射空气将有助于从圆筒表面刮去纸片或干燥通过其的纸片，或者将空气通过的开口密封在其中。

摘要： A rolling device or roller mill having a controlled-deflection roll possessing a stationary roll support or carrier mounted in a frame of the rolling mill. A tubular roll shell is rotatable about the roll support and bears thereon by means of at least one bearing or support element. The roll shell is provided at its ends with guide members which are rotatably mounted in the roll shell and which are guided on the roll support in the direction of the pressing or disengaging movement of the roll shell. The controlled-deflection roll is equipped with a scraper device having a scraper blade which, during operation, is in contact with the outer surface of the roll shell, the scraper device being rotatably mounted on the frame. At least one of the guide members has a disengaging or lift-off element which, when the roll shell performs a disengaging or lift-off movement from the operative position, abuts a part of the blade support or carrier and raises the blade off the surface of the roll shell.

摘要： A system for use in papermaking including at least two members one of which is movable relative to the other and in frictional engagement therewith wherein at least one of the members comprises an elongated flexible composite including a plurality of ceramic segments, each segment having at least two opposite surfaces that are flat and parallel. The segments are aligned in stacked relationship with their flat faces in abutting face-toface relation and forced toward each other in the direction of their composite length with a force which is sufficient to maintain the segments in compression when subjected to conditions of thermal change and/or flexing of the member during use. The ceramic member is provided with a smooth elongated working surface which defines an area of contact between the members of the system. Systems including a papermaking foil or suction device in a papermaking process, or a doctor blade are disclosed. A method for making the ceramic member is disclosed.

摘要： Disclosed herein is a fluid actuated device for oscillating a doctor blade specially adapted for paper mills, said device having a pair of inflatable members each having one side secured to a fixed plate and the other side secured to a movable plate supported between the fixed members and a water control system to alternately inflate the inflated members to move the movable plate relative to the fixed plates, the motion of the movable plate being transmitted to the doctor blade to be oscillated. Control is effected by a variable exhaust line restriction and a solenoid valve actuated by a remote pulse forming timer capable of actuating many such devices without modification.

摘要： A DOCTOR IS DISCLOSED HAVING A PIVOTABLE DOCTOR BACK PARALLEL TO AND SPACED FROM A ROLL OF A PAPER MAKING MACHINE. A BLADE CARRIED BY A BLADE HOLDER IS RESILIENTLY CONNECTED TO THE DOCTOR BACK BY A THIN PLATE OF SUBSTANTIAL WIDTH AND SUFFICIENT LENGTH RELATIVE TO ITS THICKNESS SO AS TO BE RESILIENT AND SUPPLEMENT THE RESILIENCY OF THE BLADE FOR IMPROVED CONTOUR FOLLOWING AND PRESSURIZED SCRAPING OF THE ROLL. THE THIN PLATE, MADE UP OF SEVERAL SEGMENTS ABUTTING EACH OTHER ALONG EDGES NORMAL TO THE ROLL, EXTENDS THE FULL WIDTH OF THE ROLL AND COVERS THE SPACE BETWEEN THE ROLL AND DOCTOR BACK. THE BLADE HOLDER COMPRISES SEGMENTS WHICH OVERLAP THE PLATE SEGMENT, WITH ADJACENT BLADE HOLDER SEGMENTS HELD IN ALIGNMENT FOR BLADE INSERTION AND REMOVAL, BY AN OVERLAPPED PLATE SEGMENT.
